What is the process of smelting? Give one suitable example also.

Explanation

**Step-by-Step Solution:**

1. **Definition of Smelting**: Smelting is a metallurgical process that involves the extraction of metal from its ore by heating and melting. It typically involves the reduction of metal oxides using a reducing agent.

2. **Role of Reducing Agent**: In the smelting process, coke (a form of carbon) is commonly used as the reducing agent. The coke reacts with the metal oxide to reduce it to its elemental form.

3. **Chemical Reaction**: The general reaction for smelting can be represented as:
